Detailed explanation-1: -Assessment validity refers to the extent that a test measures what it is supposed to measure. The Standards for Educational and Psychological Testing (2014) defines validity as the “degree to which evidence and theory support the interpretations of test scores for proposed uses of tests” (p. 11).

Detailed explanation-2: -Reliability refers to the extent to which an assessment method or instrument measures consistently the performance of the student. Assessments are usually expected to produce comparable outcomes, with consistent standards over time and between different learners and examiners.

Detailed explanation-3: -Validity means that the assessment process assesses what it claims to assess – i.e. the unit of competency or cluster of units. The assessment tool must address all requirements of the unit to sufficient depth and over a sufficient number of times to confirm repeatability of performance.

Detailed explanation-4: -The reliability of an assessment tool is the extent to which it consistently and accurately measures learning. The validity of an assessment tool is the extent by which it measures what it was designed to measure.
